Abstract
The effect of 10Â at% Cr addition to Fe-alloys containing 25 and 30Â at% Al and the influence of the thermal treatment on the defect structure of these samples have been investigated by positron lifetime spectroscopy. Calculations have been performed to study the influence of Cr impurities on the lifetime associated to vacancy-type defects in both the D03 and B2 phases. The results show that Cr addition leads to a decrease of positron lifetime parameters associated with an increase of the D03 order.
